A method for estimating the state of health of an electric or hybrid vehicle battery that can be carried out while the vehicle is running includes: (a) a full charge step; (b) a first relaxation step; (c) a step of discharging to a state of charge SOC≤SOCtarget carried out in k vehicle driving cycles, for each of which the capacity Qn discharged by the battery is determined; (d) a second relaxation step at the end of the cycle k; (e) a step of determining a state of charge SOCOCV as a function of the open circuit voltage; (f) a step of determining an initial discharge capacity Qi of the new battery from SOCOCV; and (g) a step of estimating the state of health SOH of the battery from the total capacity discharged by the battery during step (c) and from Qi.
